In the not so distant future a man builds a remote doom fortress to design, create, and raise GM/GMO children. His plan is to nurture geniuses who can enact his dastardly plan to wipe out humanity, and for his children to repopulate the earth.
The man precisely designs his (let's say ten) children, and raises them in isolation, doing everything he can to make them as smart and capable as possible home schooled until he sends them out to the real world to get some higher education and life experience and networking to achieve his goals.
EDIT: Please note that the use of "children" is not a specific age reference to pre-pubescence (I rather unobservantly didn't see that this could be severely misconstrue), simply that they are the man's "children" or offspring since he created them.
How can his complete control over their nature and nurture be used to achieve the following:
- The children must be created and raised to have a deeply genuine love and empathy for each other - which importantly cannot be easily translated into empathy for outsiders.
- The children must be created and raised to find each other sexually attractive and for this to overcome the natural tendency for "siblings" (psychologically; those raised together) to be repulsed by each other.
IMPORTANT EDIT: this means relations between the individuals as teenagers or young adults, as is normal. "Children" is not used here to mean age specific reference!!
- The children must be created and raised to ensure they are loyal to each other, regardless of whether the aforementioned techniques work.
- Techniques should ideally be subtle and work in ways the children cannot anticipate, and must not be overtly forced or negative. They must not infringe upon the children's intelligence. The aim is to have these techniques make the children return to each other, and home, and their objective.
I would appreciate answers based in psychology and biological sciences (genetics, neurology, etc) to understand the processes which are a problem to achieving the goals, and so how they could be overcome.
In this case GM/GMO (Genetically Modified/Genetically Modified Organism, or "designer baby") is someone whose genome has been planned with great precision, and then has been created as a "test tube" baby in some sort of artificial womb. They do not have a biological or even surrogate mother, and they might even be a synthetic organism (a la craig venter).
